(失败!)打算补全之前没搞完的三角函数正交性相关的知识
复习:🔗 [2022-06-09 - Truxton's blog] https://truxton2blog.com/2022-06-09/ 的目录1~2.4
哎呀,很不争气,正交性一点都没看,基础知识又补充复习了一大堆。
补充的内容:

Segmented k-means
继续学习「数位语音处理」的NTU公开课
上一次学习的笔记在:🔗 [2022-03-20 - Truxton's blog] https://truxton2blog.com/2022-03-20/
从这里开始继续学习:

Discrete HMM的例子最容易理解,通过理解最后一张图片的例子可以帮助快速理解之前的GMM模型的例子。

EM算法需要指定k值
EM算法是需要指定k(cluster)的!

input 4:生成3簇GMM混合数据;input 7:GMM模型指定cluster=3
千万不要再搞错了!!!
